What is the point of #define in c++ I have been seeing code like this usually in the start of header files I've only seen examples where it's used in place of a magic number but i don't see the point in just giving that value to a variable instead.
0 in c or c++ #define allows you to create preprocessor macros
In the normal c or c++ build process the first thing that happens is that the preprocessor runs, the preprocessor looks though the source files for preprocessor directives like #define or #include and then performs simple operations with them. #define simply substitutes a name with its value Furthermore, a #define 'd constant may be used in the preprocessor You can use it with #ifdef to do conditional compilation based on its value, or use the stringizing operator # to get a string with its value.
#define width 10 is a preprocessor directive that allows you to specify a name (width) and its replacement text (10) The preprocessor parses the source file and each occurrence of the name is replaced by its associated text. The #define directive is a preprocessor directive The preprocessor replaces those macros by their body before the compiler even sees it
Think of it as an automatic search and replace of your source code
A const variable declaration declares an actual variable in the language, which you can use.well, like a real variable Take its address, pass it around, use it, cast/convert it, etc Is it better to use static const variables than #define preprocessor Or does it maybe depend on the context
What are advantages/disadvantages for each method? As far as i know, what you're trying to do (use if statement and then return a value from a macro) isn't possible in iso c.but it is somewhat possible with statement expressions (gnu extension) I've found that this works on gcc and clang by default:
